REVERSIBLE TOOL-CHUGK-SUPPORTING MEANS.

Application filed June 2,

My invention relates to tools, more particularly to reversible tool-chuck supporting means, and the objects of my invention are: first, to provide a deviceof this class in which two or more tools may be quickly used in successive order, thereby providing a device desirable for compact tool-kits; second, to provide a device of this class which saves the time of changing tools when used in successive order; third, to provide a device of this class which is easily and quickly reversed or changed; fourth, to provide a device of this class which may be made either as a solid tool or as an attachment for a brace; fifth, to provide a device of this class which will allow the quick changing of tools by two simple movements and does not necessitate the changing or removing of the too-ls from the chuck; sixth, to provide a device of this class which is especially adapted for use where it is desirable to use a drill or bit and screwdriver in successive order; and seventh, to provide a device of this class which is simple, economical and sturdy of construction, durable, efficient, and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear'hereinafter, my invention con sists of certain novel features of construction, combination, and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a par of this application, in which:

Fig. 1 is a longitudinal sectional view of my device through 1--1 of Fig. 2, with parts and portions shown inelevation to facilitate the illustration; Fig. 2 is a side elevational view thereof at a right angle thereto; 3 is a fragmentary longitudinal section through 33 of Fig. 1; and Fig. 4 is a trans verse sectional view through 44 of Fig. 1.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

The chuck shank supporting member 1, chuck shank 2, chuck shank locking member 3, and spring 4, constitute the principal parts and portions of my device.

The chuck shank support 1 is U-shaped with legs l connected at right angles to the cross or end member 1. The cross member 1 may be an integral part of a brace or may be made as shown, having a shank 1, which 1927. Serial No. 195,883.

extends outwardly from and is centered upon the end member 1". This shank may be shaped similarly to the construction of bit ends adapted to fit in the conventional brace, as best shown in Figs. 1 and 2. The legs 1 extend downwardly from the cross member 1 and are parallel to each other. Near their lower ends are oppositely positioned,circular openings 1 adapted to receive and revolubly support the chuck shank member 2. Near the top and bottom of both legs 1 are slots 1 adapted to receive a portion 3 of the chuck shank locking member 3. The chuck shank member 2 is substantially X-shaped with the cross legs 2 and 2 at right angles to each other. The leg 2 is square, but is rounded near each end at 2 and adapted to be revolu v bly mounted in the holes 1 of the legs 1*. The ends of the legs 2 are flattened and form heads 2, which keep it from sliding endways in relation to the legs 1. The legs2 of the shank member 2 are centered on the legs 2 and threaded to receive the conventional chucks C. The chuck shank locking member 3 is U-shaped similar to the chuck shank supporting member 1 and fits loosely within it. The member 3 has legs 3 which are parallel to each other and at right angles to the cross member 3*. The lower portion of each leg 3 has a square notch 3, which fits over the square portion of the shank 2 and locks it in the proper position, as shown best in Figs. 1 and 3. On the sides of the legs 3 are small outwardly extending lug portions 3, which fit into the slots 1 and prevent any movement except the necessary up and down movement of the member 3in relation to the member 1. Interposed between the upper portion of the cross member 3 and the lower portion of the cross member 1 is a spring 4, which tends to force the locking member 3 downwardly in relation to the supporting member 1. The spring is held in place on the under side of the cross member 1 by a screw 1. The spring 1 may be of any conventional type, either a leaf or aspiral one.

To change the tool, the member 3 is pressed upwardly in relation to the member 1 until it assumes the position shown by the dotted lines in Figs. 1 and 3. The chucks are turned around a half turn and the member 3 is released. It then locks the chuck shank in position for use.

Though I have shown and described a particular construction, combination, and arrangement of parts and port-ions, I do not wish to be limited to this particular construction, combination, and arrangement, but desire to include in the scope of my invention, the construction, combination, and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l

1. A device of the class described, including a multiple-ended chuck shank, a support for said chuck shank, a means mounted therein for locking said shank in any desired position, said chuck shank being revolubly mounted in said shank support, said lockmg means being slidably mounted in said supporting means, means tending to hold said locking means in locked position on said chuck shank, and means on said chuck shank supporting member adapted to fit in any conventional chuck.

2. A device of the class described, including a multiple chuck shank, a U-shaped supporting member, said chuck shank being revolubly mounted in said U-shaped supporting member, a U-shaped locking member slidably mounted between the legs of said supporting member, and a spring member for retaining said locking member over and locking said chuck shank member.

3. In a tool support of the class described, an inverted U-shaped member, a square multiple chuck shank revolubly mounted between the members thereof, and another inverted U-shaped member reciprocally mounted in said first-mentioned U-shaped member provided with square slots adapted to engage the square portions of said shank for locking the same.

4. In a tool support of the class described, an inverted U-shaped member, a square multiple chuck shank revolubly mounted be tween the members thereof, another inverted U-shaped member reciprocally mounted in said first-mentioned U-shaped member provided with square slots adapted to engage the square portions of said shank for locking the same, and means tending to move said inverted U-shaped members relative to each other.

5. In a tool support of the class described, an inverted elongated outer U-shaped memher having a shank portion at its upper end, a double-ended shank member adapted to receive conventional chucks at each end and having a laterally extending axle portion intermediate its ends, bearings in the lower end of said outer U-shapcd member for receiving said axle portion and rotatably mounting said shank member, an inverted elongated inner U-shaped member slidably mounted within said outer U-shaped member and adapted to straddle said chucks, and means for forcing the lower end of said looking member in engagement with portions of said axle member for locking said shank member in the longitudinal axis of said outer U-shaped member.

6. In a tool support of the class described, an inverted elongated outer U-shaped memher having a shank portion at its upper end, a double-ended shank member adapted to receive conventional chucks at each end and having a laterally extending axle portion intermediate its ends, bearings in the lower end of said outer U-shaped member for receiving said axle portion and rotatably mounting said shank member, an inverted elongated inner U-shaped member slidably mounted within said outer U-shaped member and adapted to straddle said chucks, spring means positioned between the upper end of said U-shaped members for normally forcing said inner U-shaped member into locking engagement with said axle member and locking said shank member in the longitudinal axis of said outer U-shaped member, and means for limiting the longitudinal movement of said inner U-shaped member.

In testimony whereof, I have hereunto set my hand at Fresno, California, this 25 day of March 1927.

LEE ROY CORDRAY.
